From 22234f1375d28803074405497ea61315fb37240d Mon Sep 17 00:00:00 2001 From: "Miss Islington (bot)" <31488909+miss-islington@users.noreply.github.com> Date: Thu, 8 Nov 2018 23:35:05 -0800 Subject: [PATCH] bpo-35194: Fix a wrong constant in cp932 codec (GH-10420) This typo doesn't affect the result because wrong bits are discarded on implicit conversion to unsigned char, but it trips UBSan with -fsanitize=implicit-integer-truncation. https://bugs.python.org/issue35194 (cherry picked from commit 7a69cf47a9bbc95f95fd67c982bff121b2a903cb) Co-authored-by: Alexey Izbyshev --- Modules/cjkcodecs/_codecs_jp.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/Modules/cjkcodecs/_codecs_jp.c b/Modules/cjkcodecs/_codecs_jp.c index 2c7788a64581..3a332953b957 100644 --- a/Modules/cjkcodecs/_codecs_jp.c +++ b/Modules/cjkcodecs/_codecs_jp.c @@ -40,7 +40,7 @@ ENCODER(cp932) if (c == 0xf8f0) OUTBYTE1(0xa0); else - OUTBYTE1(c - 0xfef1 + 0xfd); + OUTBYTE1(c - 0xf8f1 + 0xfd); NEXT(1, 1); continue; } -- 2.47.3
